D( Y )
Y-3 = 0
Y-3 = 0
Y-3 = 0
Y-3 = 0 // + 3
Y = 3
Y in (-oo:3) U (3:+oo)
2/(Y-3) = 2/7 // - 2/7
2/(Y-3)-(2/7) = 0
2/(Y-3)-2/7 = 0
(2*7)/(7*(Y-3))+(-2*(Y-3))/(7*(Y-3)) = 0
2*7-2*(Y-3) = 0
20-2*Y = 0
(20-2*Y)/(7*(Y-3)) = 0
(20-2*Y)/(7*(Y-3)) = 0 // * 7*(Y-3)
20-2*Y = 0
20-2*Y = 0 // - 20
-2*Y = -20 // : -2
Y = -20/(-2)
Y = 10
Y = 10
